Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

2015 Ford Focus Sedan is fresh-faced and ready to defend its Most Popular crown

Ford has made an art of deeper-than-normal midlife updates since the 2010 Fusion, a strategy that has allowed it to keep models looking fresher in showrooms for longer without needing full redesigns. Instead of slight touchups to light fixtures, new paint colors and perhaps new wheel patterns, Ford has been digging deeper, with significant sheetmetal changes and very different front-end looks, along with an increased emphasis on new in-car technologies to keep models vibrant. Other automakers are following this trend, and Ford itself is continuing on the path with this new 2015 Focus Sedan.
There's a handsome new SE Sport Package that includes a firmer touring suspension, modest body kit and 17-inch wheels.
We first saw this sleek Aston Martin-like nose fitted to a Focus at the Geneva Motor Show last month, but Ford only showed the new look on the five-door hatchback - this is the first appearance of the sedan, which will bow at next week's New York Auto Show. The front end treatment is the same, with a new hood, new headlamps incorporating LED accents, a different grille shape and a completely revised lower fascia that does away with the 2014 model's controversial triangle-shaped corners and gaping intakes. The rear gets a new two-piece, laser-brazed trunk lid with new taillamps, but the overall look is quite similar to last year's car. In any case, the refreshed look brings the Focus sedan more in line with the design of Ford's other recently reworked cars, including the Fusion and Fiesta.

2015 Ford Mustang spied on video for the first time

Not many cars will continue to hold our rapt attention quite like the upcoming redesigned 2015 Ford Mustang, codenamed S550 internally. Earlier this month, we brought you the first spy photos of a next-gen Mustang prototype out testing, and even though expertly placed cladding concealed the pony car's new shape, we could tell that underneath was hiding an altogether new form inspired by the Evos Concept from 2011.
Today we give you some video of what looks to be the same Mustang prototype, which you can watch below, and while the budding director behind the camera wasn't able to capture much in the way of the engine's audio signature, we can see the car in motion for the first time and compare its relative size and shape to the S197 Mustang GT that's on its tail.
